SPECIFICATION forming part of Letters Patent No. 692,195, dated January28, 1902. Application led .Tune 23., 1898. Serial No. 684,213. (Nomodel.)

To ctZZ whom, #may concern.-

Be it known that I, LoUIs ARsNn DsY, a subject of Her Majesty the Queenof Great Britain, residing in the city and district of Montreal,Province of Quebec, Canada, have invented certain new and usefulImprovements in Machines for Unraveling Knit Goods; and I do herebydeclare the following to beafull, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in machines for unraveling knitgoods.

The object of my invention is to provide a device of this character bymeans of which the threads composing the knitted portion can be readilyunwound onto suitable reels.

A further object is to provide mechanism for varying the velocity of thereel, each reel having an independent mechanism.

A further object is to provide a holder for the knitted goods which willreadily adapt itself to the size of the piece being unraveled.`

To these ends my invention consists in the improved construction andcombination of parts, as hereinafter fully described, and particularlypointed out in the appended claims. v

In the drawings, in which similar numerals of reference indicate similarparts in all of the views, Figure l is a front elevation of myimprovedmachine. Fig. 2 is an end elevation. of the same. Fig. 3 is auend elevation of the end opposite to that shown in Fig. 2. Fig. 4 is ahorizontal sectional view showing the device for holding the knittedgoods. Fig. 5 is a front elevation of a portion of the machine, showingthe parts on an enlarged scale. Fig. 6 is a vertical transversesectional view taken on the line 6 6 of Fig. 5. Fig. 7 is a sectionalView of a portion of the Fig. 8 is a sectional View taken on the line ofFig. 6. Fig. 9 is a sectional view taken on the line9 9 of Fig. 5.

Figi lOis a sectional view of the clutch and its operating mechanism.

of tubular portions forming the main portion of underwear, ttc., bymachinery that by reason of the breaking of the thread and othercauses,which are apparent to those who 'operate knitting machines,portions of the .knitted tube are cut out and generally thrown away aswaste. The threads composing these knitted portions are capable of usein other portions; but such threads may be unraveled or unwound in orderthat they may be again placed on the bobbins ready for use. Whileseveral machines have been made to do this work, these machines allfailed to properly unravel the threads by reason of the fact that in theknitting of goods the threads are used in unequal quantities, somethreads being used to a greater extent than others. In the unraveling ofgoods of this kind it Will be readily seen that to wind the threadproperly the reels to contain such thread'must take up the threadsasfast as they are unraveled, and for this reason the reels must becapable of being rotated at varying speeds, which can be readilyadjusted as may be found necessary bythe operator ot' the machine. Asthe tubular knitted portions varyin size, it is desirable that theholder for these portions may be adjustable in order that fewerauxiliary parts are required for the machine. It is to provide alnachine having these advantages and eliminating the disadvantages inmachines of this character that-I have prepared a construction such asshown in the drawings, as hereinafter described and claimed.

1 designates a standard, which is preferably mounted on legs 2, forminga tripodmount such as shown in Fig. 4. The forwardly-extending leg 2 isprovided with an upwardly-extending rod or shaftA 3, having its upperend 4t conical-shaped, adapted to receive the cap 5 of a tubular casing6, which casing is' adapted to be placed on and have rotation about saidshaft 3, as best shown in Fig. 7. The lower end of the casing 6 isprovided with a collar 7, having radial arms 8, each of said armsyhaving depending lugs 9, provided with openings 10. The openings 10 areadapted to receive one end of spring-rods 11, which rods are preferablybent in the manner shown in Figs. 1 and 2, the upper ends being adaptedto be placed in suitable openings 12, formed in the ilange 13, formingpart of the cap 5. By this construction it will be seen that the rods 11can be readily placed into or out of position and that the diameter ofthe knitted portion held by said rods can be varied by changing theposition of the lower ends of the rods 11 in the openings 10. lt willalso be seen that the casing 6 will be readily rotated, inasmuch asthere is practically no frictional resistance to its rotation, and thuseliminate all danger of the threads becoming broken by the tension ofthe operating parts.

Secured to the standard 1 is a semicircular frame 14, to the upper sideof which are secured suitable eyes 15, through which the various threadscomposing the knitted portion are adapted to be passed onto the reels.If desired, the portion of the frame 1-1 may be varied vertically byplacing suitable openings in the standard 1.

To the upper face of the standard 1 is secured a plate 16, extendinglengthwise and adapted to support the mechanism now to be described, thenumber of mechanisms used being regulated by the number of threads beingreeled. The plate 16 is provided with front and rear upwardly-extendingportions 17 18, which portions are adapted to form bearings for thetransverse shaft 19, one for each reel used. Mounted slidably on eachshaft 19 is a frictional contact-roller 20, which roller is xedly heldto have a rotatory movement with said shaft by means of a block 21, heldin contact with a cut-away portion 22, formed on the shaft 19, bymeansof a suitable resilient buffer 23, mounted between the block 2l and aset-screw 24:. While the roller 2O will be held Xedly as regards itsrotatory movement, yet it will be obvious that its position may bechanged slidably on Said shaft, the block 21 sliding in the cut-awayportion 22. The roller 20 is adapted to contact with the face of a disk25, which disk has its periphery provided with a groove 26, within whichthe rounded periphery of. the reel 27 is adapted to be placed, the reelreceiving the movement by frictional contact with the groove 26 of thedisk 25. The disk 25is pivotally mounted in a bearing 28, formed in anupright 29, which is removably secured to the front of the plate 16. Theshaft of the disk 25 extends longitudinally in said bearing and has theend opposite to that containing the disk 25 adapted to be contacted by asuitable spring 30, connected to the upright 29. By this construction itwill be seen that the disk 25 will be held tightly against the face ofthe contact-roller 20, from Which it derives its movement regardless ofthe position the contactroller 20 may be placed on the shaft 19. Thereel 27 is removably mounted on the upright 29 and is provided withsuitable thread-carrying pins 31. The position ot' the contactroller 2Ois regulated by the raising and lowering of a suitable handle 32,pivotally mounted on a forwardly-extending portion 33 of the upright 29,said handle being in the formof a bell-crank lever, the lower end ofwhich is provided with a rearwardly-extending bar 34, which is providedwith an adjustable collar 35, having an extension '36, adapted to bepassed into an annular recess 37, formed on the roller 20. It will beobvious that adownward movement of the handle 32 Will cause the bar 34:to be pushed rearwardly and that this movement of the'bar will cause thecontact-roller 2O to -be moved rearwardly on the shaft 19 acorresponding distance and that an upward movement ot the handle willcause these parts to move in an opposite direction. The extension 33 isprovided with suitable eyes 38, through which the threads are adapted topass onto the pins 31, the threads passing from the knitted portionupward through the eyes 15 to and through the eyes 38 and onto the pins31. By this construction it will be readily seen that as the shaft 19,the rear end of which is provided with the grooved pulleys 39, isrotated the contact-roller 20 will coact with the face of the disk 25and cause it to be rotated in its bearing 28 and that the reel 27, beingin frictional contact with the disk 25, will receive a correspondingmove- 9 ment, which serves to wind the unraveled threads onto the pins31. As hereinbefore explained, it is desirable that the speed of thereels be changed as desired, and inasmuch as the pulleys 39 aretraveling at the same speed by reason of the construction shown in Fig.11 the velocity of the disk 25 must be varied, and this is accomplishedby means of the mechanism operated by the handle 32. As thecontact-roller 2O is moved toward the center of the disk 25 the velocityof the disk will be increased in an obvious manner, while a movement inthe opposite direction will cause a decrease in the velocity of the saiddisk. It will be seen that at all times the speed of the reel is underthe control of the operator of the machine and that its speed can beregulated without stopping the machine, thus making it capable of minuteadjustment at all times. When the reels have been filled with thethreads, they are removed from the upright 29 and new reels inserted.The thread on the reels is then wound onto bobbins and is ready forfurther use.

To drive the various pulleys 39 so that the reels may each be rotated inthe same direction, I have provided the arrangement shown in Fig. 11,which is a diagrammatic view of the arrangement of pulleys and the beltwhich operates them, taken from the rear of the machine. The belt iscarried over the inclined pulley 40, formed at the end ofthe machine, itpassing over a suitable drive-pulley41, which is driven by a beltpassing over the pulley 42. The machine may also be operated by hand IOOby means of a suitable handle 43, mounted on the pulley 41. The pulley42 is preferably a loose pulley mounted on the shaft of the pulley 41and is adapted to be thrown into engagement with a flange 44, formed onthe pulley 4l, by the movement of a suitable lever 45, mounted on theshaft of the pulley 4l', said lever being provided with inclined faces46,

' which are adapted to ride on similar faces formed on a collar mountedon the shaft of the pulley 41. A spring 47 serves to prevent the lever45 from being accidentally displaced when rotated to a position to formthe contact of the pulley 42 with the pulley 41. The advantages of thisconstruction are many and include the ability to control the entiremovement of the machine, the ability to vary the velocity of each reelas may be desired, and also the ease with which the devicewill unravelthe threads from the knitted goods.

While I have shown and described the contact-roller 2O as provided witha retainingstop of a specified form, it will readily be understood thatI may form the connection between the shaft 19and the roller 2O by anysuitable construction, such as a feather and spline, if suchconstruction is found desirable.
